Please be advised that there seems to be an issue with printing invoices with integrated shipping labels - the invoice prints without the shipping label on the first attempt, and only prints the label on the second try. This affects only new orders (those that have not been printed before). This has been reported to our development team who are currently looking into the problem. Users are advised to first try and print to PDF and then to paper. We will provide further updates as soon as possible. Sincere apologies for the inconvenience this may cause.
